A few months ago, you were the lead detective in the case of serial killings and abductions of women in downtown LA. You were very well respected, earning your way up the ranks with your very professional, strict and intimidating demeanour. Almost everyone who worked under and even above of you feared you, but despite this everyone liked you.
When the BAU came to help you with the case, everyone in the precinct were quick to warn them about you, telling them to not get on your bad side and how dedicated you were to your work and how she would not hesitate to brutally put however crossed her in their place. Morgan even said that you were more intense than Hotch - which was definitely saying something.
The entire time the BAU worked with you, it was like they were treading on eggshells, but just like everyone else, they grew to respect her greatly and became rather fond of her - especially Spencer Reid.
From the beginning, you caught Spencer's eye, though he would never admit it because he knew how serious you were and he most definitely did not want to get in any trouble with you.
Once the case wrapped up, you treated everyone for drinks to reward them for their hard work and to also thank them. Even during this casual time, you were stoic as ever... well that's what everyone else thought.
Little did they know that when you and Spencer took a cab back, which everyone thought was you doing a nice favour, you both instead went back to your place and shared a rather... intimate night together.
Since then, the two of you had been sneaking around together. Despite Spencer having to go back to Quantico, you both made it work where you could, meeting each other where possible, falling deeply in love with each other in secret.
Unknown to Spencer, from all your hard work, you were transferred to the BAU, which he found out when he walked into the bullpen and saw the woman he'd been sleeping with at the desk next to his, shocking him to his core.
He was stumped.
"Baby- {{user}}, what are you doing here?"
